-# Device Dashboard via RNDIS on an RP2040
-
-Your headless Raspberry Pi Pico-based hardware can also have a device dashboard on a web browser when you connect it to your computer via USB
-
-- See detailed tutorial at https://mongoose.ws/tutorials/rp2040/pico-rndis-dashboard/
-
-Note for Mac users: For this example to run on Mac, please set `DUAL_CONFIG=1` in `CMakeLists.txt` before building; this enables CDC-ECM. Please notice that Windows may not recognize the mass-storage device in that case.

-# Remote MQTT Device on an RP2040
-
-Your headless Raspberry Pi Pico-based hardware can also be a remote gadget when you connect it to your computer via USB
-
-For the USB specifics, see this related tutorial at https://mongoose.ws/tutorials/rp2040/pico-rndis-dashboard/
-
-See this tutorial to control your device: https://mongoose.ws/tutorials/mqtt-dashboard/
-
-For this to work, you need your computer to act as a router (gateway) and NAT for your device.
-
-## Linux setup
-
-Enable "masquerading"; the quick and simple options are:
-
-``` bash
-sudo iptables --flush
-sudo iptables --table nat --flush
-sudo iptables --delete-chain
-sudo iptables --table nat --delete-chain
-
-# Do masquerading
-sudo iptables -t nat -A POSTROUTING -o yourifc -j MASQUERADE
-# enable routing
-sudo echo 1 > /proc/sys/net/ipv4/ip_forward
-```
-
-Where `yourifc` is the interface that is connected to your network
-
-## MacOS setup

+# RP2040 / RP2350 Mongoose example
+
+This example can be built for both RP2040 and RP2350 targets.
+
+## Set target board
+
+By default, it builds for RP2040 target. If you want to change the target
+board, edit `CMakeKists.txt` and set the board, for example:
+
+```cmake
+set(PICO_BOARD pico2_w)
+```
+
+## Edit WiFi credentials
+
+For WiFi examples, edit `wifi.c` and set WiFi network name and password.
+
+## Build and run
+
+Make sure you have `picotool` installed. Then run:
+
+```sh
+make build flash
+```
+
+Start serial console to see the debug output.
+
+See detailed documentation at https://mongoose.ws/docs/guides/rp-tcpip-stack/

+This example can be built for both RP2040 and RP2350 targets.
+
+## Set target board
+
+By default, it builds for RP2040 target. If you want to change the target
+board, edit `CMakeKists.txt` and set the board, for example:
+
+```cmake
+set(PICO_BOARD pico2_w)
+```
+
+## Edit WiFi credentials
+
+For WiFi examples, edit `wifi.c` and set WiFi network name and password.
+
+## Build and run
+
+Make sure you have `picotool` installed. Then run:
+
+```sh
+make build flash
+```
+
+Start serial console to see the debug output.
